*Single password on any sites = Unsafe

Several websites have the member management system which often used SHA1 or MD5 to encryption for translating plain text passwords of any users then kept in their database. Nowadays, there are some algorithms such as “Brute-force search” that can use for finding out that what is the original plaintexts that are keyed in by any users. After knowing of a plain text password, it may be used for login to any websites that you use your single password for registering to be a member. I intend to put this post as the category of Android because I will use the simple android application to explain you about this dangerous thing that the most people did. Especially, the ATM password that the authorize people in financial institute never tells us about their encryption which they implemented in their systems. However, if they told us, the hacker will get this benefit of the narrow scope of decryption too. So we should protect ourselves as best as we can.
